If OK, we'll start to make patchset. Sure, yes, the crash utility can always support another dumpfile format. It's unclear to me how similar SADUMP is to diskdump/compressed-kdump. Does your internal version patch diskdump.c, or do you maintain your own "sadump.c"? I ask because if your patchset is at all intrusive, I'd prefer it be kept in its own file, primarily for maintainability, but also because SADUMP is essentially a black-box to anybody outside Fujitsu.
